About the A-5 Absolute Pressure Transducer

Model A-5 pressure transducers are all-welded stainless steel sensors built for rugged industrial applications that require high accuracy and measurement stability. Pressure ranges span from 0.5 psi to 60000 psi. They utilize complete four-arm 350 ohm strain gage bridges. The Model A-5 is available with a variety of options for extended temperature operation, electrical terminations and high-level outputs including 5 Vdc or 10 Vdc and 4 mA to 20 mA. Most high-level output models have internal shunt calibration circuits as a standard feature to allow easy set-up of the sensor to the data system. An optional internal signature calibration chip provides calibration information for automatic set up with the Model SC four-or-twelve channel digital indicator.

The gage Model A-5 is a strain gage based transducer. This design references the primary pressure sensing diaphragm to the atmosphere, and provides a stable zero regardless of the transducer environment.
The absolute Model A-5 has an all-welded vacuum reference chamber assuring long-term stability.
